The present invention relates to friction-type sash holders for vertically liftable and lowerable double-hung window sashes and hasmore particular reference to .a sash holder which .also. functions as a weather seal.

More specifically, the invention relates .toa spring metal strip having complemental flanges, one for attachment to the sash and the other for spring sliding contactwith the fixedframe, said metal strip being of a length commensurate with the sash rail to which it is attached and said flanges being so constructed and sufficiently spaced as to accommodate a complementalfelt filler which, combined with thestri provides the combination friction-binding sash holderand weather seal.

In carrying out the principles of the invention, I takea strip of spring metal of appropriate resiliency, gauge and strength which is bent longitudinally between its longitudinal edges to-define the stated flanges, the attaching flange 'being relatively narrow and the friction retention and holding flange being 'of a width corresponding to the cross-section of the sash rail, thefelt'ifiller being properly cut and having a portion fitting between the stated flanges, said portionv being compressed when the flanges are together toadd to the desired sealing. properties ofthe overall device.

Qther objects and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.

In the accompanyingsheet of drawings:

Figure 1 is a fragmentary perspective view of a conventional slidable window sash equipped with the attachment means constituting the subject matter of my invention.

Figure 2 is a fragmentary horizontal section showing. the sash in its frame and illustrating the vmanner in which the invention functionsin relation to the sash and frame.-

Figure 3 is a view like Fig. :in fragmentary horizontal section which .may'be'said tobetaken on-theapproximate line,3--3 of Fig. 1, looking in the direction of the arrows.

Referring now to the drawings by distinguishing reference numerals, the window sash, a sliding type, which is a common type, is denoted by the numeral 5 and includesa glass panel yon-window 6 mounted in a surrounding woodenaor equivalent frame. Usually, my devices are attached to the vertical rails of the sash frame, that is, the rails which may be identified at 'I in the drawings. The outside surface of the sash is denoted at 8 and the inside surface at 9. Ordinarily, I employ two of :the attachments which are represented in the-drawings, but I am showing only one for simplification. As a matter of fact, the description of both devices would be the: same,;and a "description ofv one will suffice for both. To this end, the principal attachment is denoted. by the numeral I0 and this is formed from a strip of spring steel=of appropriate gauge which is bent between its longitudinal edges, as at II, to define a substantially Vshaped member embodying a relatively narrow attaching flange I2 and a wider friction and retention flange l3. The attaching wflange I2 is provided with screw holesto accommodate wood screws I4 and said fiangeis 'fastened'to the rail 9 so that the bend I5 is slightly inward of the surface 8. The flange I2 is approximately one-half, more or less, in width compared to the :crossesection-of the rails I. The flange I3, which is of the desired retentiveresiliency-thought to be approximately equal to the cross-section of the sash rail 1, as shown in the-drawings. This flange, sometimes referred toas-a friction shoe, is, like the flange I2, of a length commensurate with the length of the rail 1. Said flange I3 has screw holes therein. at [5. These holes or openings are primarily adaptedtopermit the screws to be inserted, by the user's :fingers, therethrough and then into the screw holesinto the flange I2. Said holes I5 give-access of a screwdriver to the screws I 4 to allow same to be driven in.

The attachment I0 characterized by the flanges I2 and I3 serves-asa sash holder. That is to say, the flange I 3 is possessed of inherent resiliency and springs ,out against the coacting surface ofthe channelway I6 in thewindow frame IT, as shown toadvantagein Fig. 2.

To add tothe utility ofv thev device and to give it the. double-function of a sash holding shoe and. weather strip or weather seal combined, I provide a filler .of. felt or equivalent packing material which is denotedby the numeral I8. Thisfillerflhas a relatively thick portion which is gluedor otherwise fastened to the sash rail .1, as-shown in. Fig. 3...- It has a narrower tapering adapter .-or insert I9 which is fitted in between the fixed andmovable flanges I2 and I3. When; the fiangel3 is in friction-retaining position, as shown in Fig. 2, the felt material is compressed firmly-betweenthe two flanges and this adds to the effective sealing properties of the felt filler. It will be noted that the portion of the felt filler which is secured in place is directly attached to the wooden rail 1 in order to provide a weather-tight joint between itself,

l8, the rail 1 and the screw-attached flange I2.

The overall invention or attachment comprises two main parts, a filler of felt or equivalent stock, and a bent metal strip constituting the attachment proper, the part denoted by the numeral (0. More specifically, novelty is predicated upon the narrow and wide flanges I2 and 13, the flange [3 being a heavy, springy element sufficient to provide the friction-retention results wanted. In addition, the felt strip coacts intimately with the flange l2 and the rail 1 and, by having the tapered insert 19, is compressed nicely between the two flanges l2 and I3. Thus, an effective two-way sash holder and weather seal is had.

Although the drawings show the attachment applicable directly to the window sash, it is obvious that such attachments may also be used by connecting one to the top member of the window frame (not shown) and another to the window frame sill (not shown). As a matter of fact, I contemplate using the invention even between the meeting rails of upper and lower sliding sashes. Primarily, however, I am interested in the simple adaptation illustrated in the drawings.

By way of summation, it is to be pointed out that the principal novelty in the invention at hand is predicated on a metal weather strip which is of general V-shaped form in cross section with the narrower flange providing the attaching and anchoring flange and the wider one providing the resilient friction shoe, in conjunction with a strip of complemental felt which is interposed between the flanges, is of a width corresponding to the wider flange and has one of its longitudinal edge portions seated in the crotch formed by the bend at the longitudinal center of the metal strip.

In view of the foregoing description taken in conjunction with the accompanying drawings, it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention, the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and within the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. In a structure of the class described, in combination, a conventional-type slidable window sash including a sash frame and a window panel, a metal strip of a length corresponding to the length of one of the vertical rails of the sash frame, said strip being bent intermediate its respective longitudinal edges to provide a member of V-shaped cross-section embodying an attaching flange and a complemental friction flange, said friction flange bein resilient, constituting a retention shoe and being of a width substantially equal to the cross-sectional thickness of said one vertical rail, said flanges being provided with coacting screw holes, said attaching flange being narrower than the friction flange, and a strip of compressible felt of a cross-section substantially equal to the crosssection of said one rail and substantially corresponding in width to the cross-sectional width of said friction flange and reduced in thickness to provide a wedge-shaped adapter, the latter overlying said attaching flange and thus projecting snugly into and filling the crotch of said V-shaped member, the inner longitudinal edge portion of said strip of felt projecting beyond the corresponding inner longitudinal edge of said attaching flange and being superimposed against and glued to the coacting edge surface of said one rail, said inner longitudinal edge being flush with the inwardly facing flat surface of said one rail, said friction flange being normally sprung, through the medium of its inherent resilient properties into spaced divergent relationship with the coacting surface of said felt strip and being adapted, when in use, to be forcibly pressed into firm direct contact with said coacting surface, whereby said felt strip shall be clamped between said one rail and said flanges.

2. A sash frame attachment of the class shown comprising an elongated weather strip of general V-shaped form embodying a relatively narrow attaching and anchoring flange adapted to be secured to an edge of one of the vertical rails of a sash frame and a correspondingly elongated but wider resilient flange opposed to the attaching flange and diverging therefrom and constituting a friction shoe, and a felt filler of a length corresponding to the lengths of said flanges, said filler being of a width approximately the same as the width of the friction shoe and having a relatively thick longitudinal edge portion which is adapted to be glued or fastened to the stated rail and having a thinner wedge-shaped adapter portion fitting into the crotch of the V- shaped weather strip and interposed between the stated flanges, said V-shaped weather strip and felt filler when combined therewith providing a unit which is substantially of a cross-section corresponding approximately to the cross-section of the sash rail on which the unit is adapted to be"'mounted, and the relatively thick longitudinaledge portion of said filler being flush with the corresponding free edge portion of said wider flange when the latter is forcibly pressed into contact with said filler.
